Front-terminal, fixed four-pole XT2 design reduces wiring complexity and speeds panel assembly, delivering lower commissioning costs and fewer field faults. The thermomagnetic release TMA provides rapid overload and short-circuit protection, improving device longevity and system reliability in transformer feeds and motor circuits. With 80 A rated current and a 400–800 A instantaneous setting, users can cover a wide range of industrial loads without swapping devices, simplifying spare parts and inventory management. Energy efficiency is enhanced by a low per-pole power loss of 5.8 W, contributing to cooler panel environments and reduced cooling costs over the lifecycle of the installation. Compliance and lifecycle data, including EPD, RoHS, REACH, and CMRT information, support procurement decisions while enabling end-of-life planning and responsible disposal. Compatibility with the SACE Tmax XT family and front-terminal configurations simplifies integration into existing switchgear and distribution boards, with detailed wiring diagrams and manuals facilitating installation and future upgrades.

FAQs
Yes. The unit is designed as part of the SACE Tmax XT family with front-terminal terminals and 4P configuration, ensuring straightforward mounting in XT style enclosures. It supports busbar connections from 32.5 to 100 mm² and a 6 N·m tightening torque, aligning with XT installation practices and minimizing retrofits.
It is a 4-pole MCCB rated at 80 A with a setting range of 56–80 A and a rated short-circuit instantaneous setting of 400–800 A. Rated voltage is 600 V (AC) / 500 V (DC), and it supports UL489/CSA standards with a short-circuit rating suitable for common industrial feeders in distribution panels.
Ideal for industrial power distribution, transformer feeders, and switchgear where compact protection is needed. The front-terminal design and TM A release simplify installation and field service, while the 80 A rating and high Ics settings provide robust protection for motors, transformers, and critical loads in manufacturing and processing environments.
The device carries UL/CSA certification, CE conformity, RoHS and REACH declarations, CMRT for conflict minerals, and an EPD for Tmax XT. Additional documentation includes the EC Declaration of Conformity, UL certificate 1SDL000163R0112, and recycling/disassembly guidance, aiding regulatory reporting and end-of-life planning.
With mechanical durability up to 25,000 cycles and electrical durability up to 8,000 cycles, the XT2 MCCB supports long service life in active duty environments. Low heat generation (5.8 W per pole) improves panel temperatures, reducing cooling costs, while front-terminal access simplifies maintenance and testing, delivering lower total cost of ownership.
